Improvement in rotary hair-brushes



UNITED STATES PATENT OFFICE WILLIAM G. NUTSFORD AND WILLIAM GLASGOW, OF CHICAGO, ILLINOIS:

IMPROVEMENT IN ROTARY HAIR-BRUSHES.

Specification forming part of Letters Patent No. 166,027', dated July 27, 1875; application led April 17, 1875.

To all whom 'it may concern Beit known that we, WILLIAM G. NUTS- EoED and WILLIAM GLAseow, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Rotary Hand HainBrushes, of which the following is a specification:

The presentinvention relates to rotary hairbrushes which are operated by hand; and consists in the construction of tWe frame and parts connected therewith.

Figure l represents a longitudinal section of the entire apparatus for operating the brush. Fig. 2 is a vertical section of Fig. 1, taken on the line a: x. Figi. 3 is an end View of the brush, looking from the line a' m.

Similar letters of reference indicate corresponding parts.

A represents the rotating hair-brush, which is confined in the frame B by pivots G C. D is an upright branch of the frame, which carries the gear-Wheel E, which is on the pivot C', and the gear-wheel F, which is on the crankshaft G. These gcar-wheels mesh together.

The pivot-bearing O is conned in the upright D by means of a collar on each side of the wheel, and both gears revolve in a recess inthe upright, which is covered by the inside plate H. 4I is a pin through the pivot O. J is a wire or rod, doubled, as seen in Fig. 3, to form a projecting flange on each side of the pivot-pin I, by means of which motion is imparted to the brush. The upright D is hinged by a joint-pin, N', to the end of the bar J of the frame, and is kept in position by the han die K, which is hinged by a joint-pin to ears L of the stal Mof the frame. The outer end of the handle is fastened to the upper end of the upright by a snapfastening, N. When the spring-hook O is pushed back the handle may be raised, and then the end of the upright maybe pushed inward, and the pivotpin C is withdrawn from the head of the brush. To the staif M are attached two tubes,

R and S, which slip together as a telescopic joint. In the inner tube S is a spring, O', attached at 011e end to the base of the stan M, as seen at P, and at the other end to the hook Q, which latter is attached by a hook to the ceiling of the room. This spring O may be of rubber, or be a spiral Wire, as may be desired, and sufficiently strong to support the weight of the frame and brush. The telescopicjoint gives the brush full play as to height, while the inner tube S turns within the outer tube as a swivel-joint, so that the brush may be turned and revolved in any position to be applied to all parts of the head. T is the crank, by means of which the brush is revolved. U U are screws, the lower one of which secures the inner tube S to the base M, and the upper one secures the outer tube R to the hook Q and head -piece V. This hook Q may be connected with a horizontal rod by means of a sliding ring, instead of to a hook in the ceiling, to allow the brush to be moved from chair to chair.

We do not confine ourselves to the precise form and arrangement ofthe parts shown, as variations may be made in many Ways without departing from our invention.

Having thus described our invention, we

the purposes described.

WILLIAM G; NU'ISFORD. WILLIAM GLASGOW.
